A contact switch works by physically connecting or disconnecting two metal contacts when an object applies pressure or movement to the switch. This change in contact state is used to control the flow of electrical current in a circuit, triggering actions such as turning on a light or activating a device. Contact switches are commonly used in various applications, including push-button controls and door sensors.

Why wont your parking lights or dash lights work on your 1999 mustang?
could be a fuse problem, and then again it could be in the switch its self. Make sure your getting contact in your light switch.
